Definitely a neighborhood gem, probably overshadowed a little but their neighbor Hong Kong Royal but there is a big difference between Hoanh Long's vietnamese cuisine and Hong Kong Royal's cantonese cuisine and dim sum. Both are good but just different. The most talked about dish for Hoang long is probably their spring roll appetizer with peanut sauce which I think lives up to the hype.
Pros: Very good bbq pork, spring rolls
Cons: Somewhat overshadowed by neighboring Hong Kong Royal
