I used to go to a business club and ate lunch here every week for about 25-30 weeks of the year from 08-10. It used to be one of my favorite places then in 2009 suddenly something weird happened: The portions decreased by 1/3 and the prices went up by 20%. Ever since then I have stopped going there frequently and now only go there about once a month.
The food is quite good, service decent, and the atmosphere nice but when the bill comes it is kind of a shock and not a great value in my opinion.
So what I will suggest is this: Go there for the specials!
Currently on Tuesday's they have Baby Yorke's for $1 each and this is quite a deal. Halo probably has some of the best Yorke's in the city - they are so fresh and the meat is tender; they melt in your mouth. Yum.... I can't wait till next Tuesday!
Monday's is a prime rib special $15 or $16 I believe, and you would have to look at the website for other details.
Another thing is don't forget dessert. Their dessert is amazing! This evening I went for Yorke night and was really mad; they didn't give me the fireside table I reserved (and there was all of 4 tables - it was slow) and then after ordering 10 Yorke's they ran out for the night. I was all about to axe them off my list forever and storm off when I decided I would buy dessert. Well dessert was impressive. I ordered the New York Cheesecake with Strawberry's and it was great. Very fresh, homemade (not frozen like most Calgary places!) and a good portion and price. It had a Oreo crust which was much nicer than the traditional graham cracker and hit the spot nicely and is now the reason I am going back. In fact I think it was better than the cheesecake I have ordered at The Cheesecake Cafe!
After talking with the waitress I learned that all the deserts are homemade like the Baily's Creme Berle, Baklava, Apple puffed pastry with granola and maple walnut ice creme, and a bunch of others I intend the try.
Also had tea with dessert and again I was impressed - not your typical Red Rose but instead a loose leaf tea called (Reveal?) it came in a little box and was presented nicer than any tea I have ordered at a lounge before.
So in summary: come here and eat the specials, good desserts!
