Ushabu is a small but well-decorated modern space with only 4 booths and bar seating. I was here earlier in the evening and was able to get a seat without a reservation.
I wasn't too enthused by the food itself. Ushabu is a Japanese fusion hot pot, not the shanghainese/Mongolian hot pot with the standard broths, sauces, various noodle options, gigantic shareable portions. The vegetables included arugula which was a bit odd. I wished that they had given a larger portion of mushrooms (only 2-3 pieces of oyster mushroom in the bowl) and udon noodles (4 short strands of noodle). I had the miso broth with the Ohio wagyu. The portion of wagyu was on the smaller side.
Overall, the soup was ok, not impressive. Worth paying about twice as much as for normal hot pot? I'd say no.
