Definitely a trendy spot to chill at Bar Isabel. Atmosphere was casual yet had a fine dining-feel to it, as the waiters would fold our napkins whenever one of us went to use the restroom. Music was good and the crowd was very mixed from students to families to young and elderly couples. It was somewhat loud as people usually go there as a place to socialize. Also, don't expect to have a private or quiet conversation as the tables are seated quite close to each other.
The food was great. There were two of us and initially we ordered four dishes, but then ended up ordering two more afterward. We ordered the following dishes (and it came in this order):
1) Fried squid (7.5/10)
2) Sweetbreads (8/10)
3) Ceviche (8/10)
4) Grilled asparagus and chorizo (8.5./10)
5) Scotch egg with chorizo (7/10)
6) Caramelized onion flatbread (4/10)
Several of their dishes have a highly acidic (e.g., marinated in lime juice) component to them so it would be good to try a bit of each dish here and there vs. finishing a whole dish first. I wish we had done that, but they seem to bring out one dish at a time every several minutes.
Bar Isabel is a place I'd return to for a special occasion with a group so that I can try a bit of everything; however, I find that it is overpriced for what it's worth. For two, including a beer and a glass of Riesling, the bill came to $124 including taxes.
