The building that house the Grand China Hotel is some sort of shopping centre (quite desolate to be honest), and it comes in handy if you're sightseeing around Chinatown and want to have some food in an air-con environment.
The food court is on the 5th floor, and there's usually a board listing the veggie options although it's only in Thai. You should be able to get pad thai, rad na noodles, as well as traditional Thai desserts like cheo kway.
