Thanks everyone for the advice!
I ended up booking a meal at El Ideas. Compared to other options, it was a mix of affordability and interactivity.
A little background on my choice/perspective...
To me, a unique dining experience goes beyond the food. It's how the chef + waiters/waitresses involve and, to an extent, educate you throughout the meal. Simply sitting back and being doted upon is nice, however when I drop hundreds of dollars on a restaurant, I want to be actively engaged.
The most memorable meals are those in which I play with my food, or when each meal adds to the overall experience.
I've never forgotten the 50 garnishes of lamb at Alinea, or the slew of tricks throughout a blurry, yet memorable meal at Next. And then at Elizabeth I arrived in a dragon costume for their Game of Thrones series, relishing in its "home kitchen" environment.
Some of my favorite restaurants are equally about the equilibrium of food and their environment: Red Hot Ranch is a no-fuss, perfect hot dog in a no-frills setting. Birchwood Kitchen had a welcoming air and served honest food.
My concern about El Ideas was that it tows the line on gimmicks vs quality of food, however these posts have me really excited to eat there.
Thanks again for the replies. I'm excited to see what other people have to say!
