I ate at Acqualina last night (on Lincoln at Montrose), and because I was pleasantly surpirsed and found no topics on it on Chowhound, I thought I would do a quick review if anyone ever needs it.
The decor was nice, the room cozy but not too crowded, the prices pretty good for what you get (apps ~$5-8, entrees < $20, desserts ~ $5-6), and the service was good, although a tad slow. They even gave our friend a small cup of soup to try so she could decide if she wanted to order it.
In regards to the food, I was very pleased. I had the fritto misto with remoulade sauce, and it was very well done with very fresh calamari, caper berries, red peppers. Our friends had a parsnip soup with apple essence, and it was excellent - perfect for fall.
For the entrees, my wife and I split two - the surf and turf and the beef sirloin. The surf and turf I liked (but my wife hated), consisting of breaded fish on a very cheesy and thick risotto. I thought it was good comfort food, although the fish flavor did get drowned out (and I am not sure where the "turf" was). The beef dish was excellent - medium rare with a truffle and wine reduction on mashed potatoes. Another diner had the pasta special, with fresh and dried tomatoes, scallops, and a little habanero pepper (good flavor, and nice and spicy).
For dessert, I would skip the "sticky toffee" which was mainly light banana and creme flavoring and not that great. But the coconut sorbet and champagne sorbets were very nice.
Overall, I was impressed considering I knew nothing about the place. If you are in the neighborhood, I would definately go (but you may need reservations).
