AYCE Sushi or hotpot recommendations

Hello! First time poster, long time reader lol. I have two separate questions but figured I’d ask both here. Anyhoo, I’m wondering if y’all know of any AYCE sushi places or just somewhere with some bomb ass sushi in general. Willing to travel to Gaithersburg and other MoCo areas, but prefer Rockville. I’ve tried kusshi in town square twice and was not a fan of their sushi. Their spicy tuna was lackluster and felt like a tuna paste rather than fresh tuna. I tried other rolls there too and was not impressed. Overrated in my opinion. Gyuzo in town square was pretty good and I’ll see if they have an AYCE option. But I’m open to any recommendations!

Second question: I’m also wondering if there are any good hotpot places as well. Preferably AYCE recommendations. Tried hotpot city in town square and the best thing about that place was the robot serving my drinks. Too many gnats and flies for my liking and meats weren’t great either. Nothing tasted fresh.

Thanks in advance!
