Maybe it's an expectations problem.  I've found that I occasionally need to tell friends to STOP HYPING THAT MOVIE to me, ever since Pirates of the Caribbean got so overhyped for so long by my well-meaning friends (\"Best movie ever!\" \"I laughed, I cried, it changed my life!\" \"I'm dumping my fiance in the hopes of getting Johnny Depp's attention!\") that I walked in expecting Citizen Kane.  Needless to say, it didn't work out that way.\n\nI may have made the same mistake after getting so psyched about the Yelp reviews for Mamma Mia.\n\nThe Good: The pizza here is EXTREMELY affordable.  Couple the killer lunch special ($4 for two massive slices of cheese pizza and a can of soda) with a Groupon ($20 for $10), and you create what scientists refer to as a value vortex - a deal so good it should not be able to exist stably in reality (much like antimatter).  In this case, I went with four friends, ordered five specials, paid with the Groupon, and we ended up stuffing ourselves with hot pizza and cold soda for a combined $10.  That. Is.  Awesome.\n\nThe Meh: The pizza just wasn't that flavorful.  The sauce and cheese were pretty ordinary.  It just wasn't as special as I expected.\n\nDon't get me wrong, I will be back (especially since I had the foresight to buy two Groupons).  I'm an absolute sucker for value and this is the best pizza deal around.  But don't go expecting the pizza to transport you, Narnia-wardrobe-style, to New York.*\n\n*In the unlikely event that it does, steer clear of that lady hawking the Turkish Delight on the corner.  Trust me.
