Some recommendations San Luis Obispo area recommendations...
For my cake we decided to go with Madonna Inn. We originally thought they would be ridiculously expensive, however, we went cake tasting there today and they aren't bad. First of all, the tasting was amazing. They gave us a huge amount of cake (we took 2 boxes home!). We ended up ordering an 8" decorated cake for us to cut and a sheet cake that feeds 100-125 and only spent $175!
Also, I highly recommend Giuseppe's restaurant in Pismo for a reception venue (for those of you with smaller weddings, under 100). If you hit the food/beverage budget (for the whole facility it's $2600) there is no rental fee. They set up everything for you and it's a three course meal. Ours ended up being about $30 a plate and the guests get a seated dinner with a salad, pasta dish, and whatever entree you pick!
