I've actually been coming to zenith even before I moved to Pittsburgh (I've lived here since July 2013). For the most part, as long as you don't mind sharing a table with other customers, you can get seated reasonably fast. All of their buffet and entree food has been delicious. One thing I do not like is that not all their entrees are vegan even though everything on the buffet is. Prices have gone up over the past years, but I totally understand that. This is an awesome place for brunch to bring "out-of-towers" because not only is it a restaurant but also an antique shop.
