Headed to Vegas in April and I'm looking for some of the best appetizers fellow chowhounders have had. As background I had a similar post a few years back looking for suggestions for an appetizer crawl. My husband and I prefer to eat at bars and find by having appetizers and moving from restaurant to restaurant we can put together our very own tasting menu. From my 09 post we got some great suggestions that have become staples in every trip we take to Vegas (bone marrow flan from cut, beef carpaccio at olives, tofu at roko, octopus at carnevino, lamb tongue at b&b to name a few). It's been a few years since our last trip (city center wasn't even open yet), so I'm looking for some can't miss appetizers for our trip. We're adventurous eaters but also appreciate a good chicken wing and beer so I'm open to any suggestions. Thanks in advance.
