If you want something upscale feeling but affordable I love the vibe at wusong road tiki bar. Great food too.

If you want to have the most fun, level 99 gaming in Natick is so fun. You can earn points for pretzels and fries and they serve fancy soda. It's $50 a head though (definitely get full day pass and ideally go on a weekday to avoid lines)

Myers and chang is also great and affordable.

Brassica is my favorite Boston restaurant. Bit more expensive though.

I guess all my recommendations are tapas. Tapas is so good.

My favorite hot pot is Kaze, it's cleaner and nicer than spring shabu shabu. I agree it's a great experience.
