I had lunch at Wilde last summer and found it disappointing on all fronts (service, food, cost, beer), with the exception of the space, which is very nice looking. Whenever I'm at Broadway and Belmont and want cheap, the Bagel and Stella's Diner are my two favorites. But I'm surprised no one mentioned the awesome duo of Ping Pong and Wakamono, which are just a few blocks north (no more than a 5-7 minute walk). Wakamono remains my favorite sushi place in town - they have inventive rolls, amazing and unique small plates, and though they've added a corkage fee to their byo ($5), the new wine list is cheap and decent. I haven't been to the Asian-fusion Ping Pong across the street in a while, but they have all the usual Amero-asian classics done up fresh in an environment that looks like a gay Apple store.
Don't forget to get ice cream at the little candy shop 1/2 block south when you're done.
