Haha... judging by the reviews my theory holds true - People are picky on their Indian food.
...myself included.
Well, here's my two cents on Glory (and I have tried at least 10 places in Calgary). I quite like Glory. In the last seven years I have been many, many times. Some for Bday parties and others just for a quick supper with a friend. It has rarely to never disappointed me or my friends when we have come by to overeat and roll home.
The service seems to be on par most times (not exceptional by better than some). The food comes in a decent amount of time regardless of how busy they are, and the servers are attentive to drinks, etc. I have eaten quite a number of things off the menu but the Butter Chicken brings me to a special place like no other BC's have at other places. It's really, really good. I have gone at times and eaten just this (which seems like a sin really). Other staples and favs are the gosht Korma, chicken Aftaab and Malai Kofta (delicious tender little dumplings in sauce). The Gulab Jamun for dessert is a sinful weakness that is a must have. I skip rice as its tasteless filler but overdue it on garlic naan to sop up every drop of sauce (embarrassingly). I really like their naan for making BC sandwiches as well.
For Indian - Glory remains my fav and likely will stay that way. The prices are a little high for what you get, but again when I go - I overeat until I start to sweat so I try to not go too often. Bad idea.
