Harbor Palace is the dim sum anchor of Las Vegas Chinatown, running the full Hong Kong playbook across a large room that fills up fast on weekend mornings. Trolley service goes through the room through late morning; the har gow, siu mai, and cheung fun all arrive at the quality you want, and the roast meats — available from the rotisserie counter — are a legitimate reason to visit outside of dim sum hours.
The live tanks at the entrance hold lobster, crab, and fish that can be ordered to table; the kitchen handles them well. Bring cash and a group, arrive by 10am on weekends, and expect noise. The lunch rush is the place's natural state.
