I am getting married on a farm and having the reception right there as well. The entire event will be outdoors and our menu is very picnic type food (i.e. grilled chicken, baked beans, coleslaw, potato salad). My caterer does not provide tableware (plates, silverware, glassare, etc). My question is: is it too tacky to use plastic ware? We are working with a VERY limited budget, but we are also planning on nearly 300 people. What do we do??
