Adonis excels for me in terms of being cheaper than most of the supermarkets (Whole Foods and Superstores) while having a curious selection of Middle Eastern and Mediterranean goods, prepared foods and a delicious bakery!
I drop by every once in a while for the marinated meats and a few prepared rice dishes. It's a great change from the regular monotony of rotating dinners we tend to do.
My recommendation however is that you come in early in the morning unless you enjoy being rammed in your heel by someone with a shopping cart behind you!
For me it's all about getting in and out quick fast and what I came for! If you use this game plan it may work for you! If you go late in the afternoon make sure you come with your best patience!
