Groupon is offering a 50% off The Blue Iguana Mexican Fare. My husband and I have eaten at the Park City location and thought is was quite tasty. The fine print states :

• Limit 1 per person, may buy 1 additional as a gift. Limit 1 per table. Valid only for location purchased. Dine-in only.

It looks like you can also earn 3%cash back on this deal through ebates.
