Well. This is a buffet.
If you're someone looking for an amazing buffet experience in vegas, you probably didnt click on the Garden Buffet reviews anyway. It deserves the low stars because it is such lower quality than what the trend in buffets in vegas is becoming. If you are looking for a good buffet, wiling to not be cheap, and by south point, just keep driving to the M and enjoy Studio B. Ye can thank me later.
In regards to the Garden Buffet: It's not completely miserable. If you are on a budget, it could be an option for a large quantity of food for cheap. You can go register for a club card and get an even better price for your entire party (we saved $15 for 30 seconds of work). There are some things at the Buffet that you will certainly like. A personal favorite of mine is having the live custom stir fry esque experience. I could eat plates of fresh cooked garlic beef with water chestnuts for the whole meal and be satisfied.
Do yourself a favor if you're in vegas and actually interested in a good buffet to go to Cesars, Cosmo, M, or any other myriad of buffets I love. The joint at the South Point is jut south of par.
