Two new Asian restaurants — Urban Hot Pot and Akira Ramen — are moving into the The Galvan complex on Rockville Pike. The side-by-side concepts, complete with conveyor belt, will take the vacant space between Ethan Allen and Dunkin’ Donuts. This will be the second hotpot restaurant to open in the area this year, following four-month-old Little Dipper at Rockville Town Square. “There’s a great demand for all these Asian concepts in the Rockville area,” says broker Shang Wang, who’s handled several such deals for JBG Companies. “Whether it’s hot pot, ramen, poke or bubble tea, all of them are doing really well.”
