Bar Isabel was quite the disappointment. Between two of us, we ordered four dishes to try a bit of lots of things. At the end of the night, there's not one dish that we'd go back for. The cold meats platter wasn't bad, though I feel that Spanish cured meats don't work as well for that kind of dish (as Italian would). From the main dishes, the sweetbreads with tuna was by far the best. The octopus was nothing special, and the lentil with mushrooms dish was a combo of things that didn't really add much to each other. I think they've likely changed their menu recently cause some of the dishes I saw in yelp pics didn't look like they were on the menu.
Regarding service, we were seated at the bar so we were helped by both the bartender and a server from the floor. The bartender was very friendly and helpful. The other server was very cold and barely talked to us other than to scribble down our orders. Very confusing when it came time to tip.
Edit: almost forgot one key detail: the pacing on bringing out our food. The first two dishes came out one after the other in the first 15 minutes. Then we had a 45 minute gap before we got the last two dishes together. Added to the overall frustration of the evening.
We were there celebrating a birthday, but the combination of the disappointing food and cold service made us skip dessert.
