A thoroughly enjoyable restaurant, Cafe Aion (near the college and Fox Theater) is a wonderful place for paella and delicious tapas (don't miss the fried cauliflower or the mushrooms in season. There paellas are delicious but not as large as they think (they say it serves two, which it does with appetizers, etc., but men and some could easily order just one per person). Ambience is great. It's out of the way (if you aren't near the college) but absolutely worth the drive. I've brought many friends from out-of-town and all enjoyed it immensely. If you live in Boulder, check out the many specials held on different days of the week. Despite being near the college, parking has never been a problem.

Fabulous. Staff are terrific. Delicious food with vegetarian options. I think of it as "casual elegance!"

Our second visit and did not disappoint. Waiter was happy to allow me to taste a number of the wines before settling on the choice for dinner. Dinner was excellent as usual. Desert was amazing.

For department events -- e.g., taking a visiting speaker out to lunch -- this place is just perfect. There are delicious options for both carnivores and vegetarians, and the food is always delicious. Servers are always very friendly and relatively efficient though if you need to be out of there under an hour, you will want to let them know. My favorite place on the Hill next to the university.

No draft beer. Wait staff didn't know about the wines. Food marginal. Too bad. Cool place. Sad to watch it go down hill. We won't be back.

This is our "go to" place on the Hill when you don't want fast food. And the ambiance is delightful.

A cute college town place with an out of the ordinary menu. Frittata was pretty unremarkable, French toast good.

I don't expect a restaurant on "the hill" in Boulder to be quiet and of high quality, but it WAS. The ambiance for my birthday lunch was peaceful and lovely, in a very well-decked-out space, with great service. We had the cauliflower, kale and sweet potato fries for apps and some main courses, but I was mostly distracted by the excellent iced tea and fries. I can't wait to go back for dinner! I'm glad they were open when most places close in between lunch and dinner.

Great food. Great atmosphere. Just two issues
It was 95 degrees that evening and there was no air conditioning. Waitress made us keep our silverware for every course. Will definitely return.

Good overall, but they were out of some things on the menu.

We had a mixed experience having brunch at this very casual Spanish "tapas" (sort of) restaurant. This is a casual, college campus eatery rather than an upscale restaurant. Some of the food was sublime, some just average or below par. The chai-soaked French toast was delicious, as was the house-cured bacon. I had a gazpacho thickened with bread and drizzed with basil oil -- far more sophisticated and high cuisine than the restaurant's ambiance would suggest. The Merguez flatbread was tasty (wonderful authentic seasoning on the merguez) but presentation left a lot to be desired. The description suggested a pizza-like presentation rather than the sausage on a flat piece of bread that I got. The baked eggs were a hit, but the fried chicken sandwich received a pan from my brother-in-law.

Truly the best bite in Boulder! Great location on the hill, quiet, inside is amazing, outside is cute, food is perfect. Cafe Aion never fails to satisfy.

Great Moroccan-style tapas and plates. Good Happy Hour with $2 Sangria from 3 to 5 pm and all day on Tuesday. We'll be back!

The food was very good, which saved the day for this place. The surface of our table on the patio was in pretty bad shape and the table would not sit level. Although the two female servers were pleasant, they seemed quite confused, taking a long time to bring us various parts of our meal, giving some of our order to other tables, giving us a drink order from another table (part of which they spilled on our table), and completely forgetting about certain requests (eg clean small plates after we finished our tapas.) Maybe they were overloaded, maybe they were just green or untrained, but a big improvement should be made in this area.

Hidden gem! Great service by Cassidy and the staff there. Food was delicious and were plenty of different plates for everyone and their various tastes.

It wasn't the experience I expected. Two months before when I ate lunch at Café Aion, I was impressed by the quality and depth of the food choices. That's when I decided to take by daughter there. The restaurant was out of both meals we ordered, and the substitutes were not satisfactory. Only the fresh squeezed orange and my daughter's salad were something I would recommend. There were no other diners because it was a late lunch.

We liked the paella very much. And the cauliflower tapas is a must. We were attending the Colorado Shakespeare Festival later that night, so Café Aion made it a special night.

Every dish we ordered was swimming in a sea of oil. Extremely disappointing.
