Yes, Corner Bistro does the $2 or $3 beer thing where you get 8oz at best but the burgers are amazing.
For me the best thing is to land up at Hop Devil or even Waterfront Ale house or Barcade and order a stronger beer. Pay the $5 but the alcohol content and taste (you have to like more full flavored beers for this to work) will knock you out. A single beer properly ordered is like 2 regular beers.
Go to barcade and order this:
TEN - Ithaca Beer Company - BeerAdvocate
and suddenly that $5 beer is like 2-3 beers. You can't just look at alcohol content alone, since the other substances that naturally form during brewing also "help" the cause in these full flavored beers.
