Of course you MUST GO to Bar Isabel! You must enjoy the cocktails, the small plates, the amazing wine and superb yet understated service.
WARNING:
1)If you haven't been to Spain, or other quality restaurants, you may not appreciate the attention to detail that informs the experience.
2)If you do not eat meat, if you don't enjoy sharing your food/small plates and if your preference is for a more predictable "white table cloth" (e.g. boring) experience, this is likely not the restaurant for you.
3) If you are going ONLY because the restaurant appears at the top of everyone's list, this is likely not the restaurant for you.
If you want a spectacular, creative meal in a room that is appealing despite at times a frenetic and cacophonous environment, this is the restaurant for you.
PS - don't be blindsided/distracted by the celebrity you will see in the room - the Bar Isabel staff clearly are professionals. Kudos to Bar Isabel for making everyone feel they are a valued and wanted customer.
