I've been to the Grasshopper Cafe many times. For a new restaurant, they have a great menu, and a friendly staff. The owners are a true success story - worked for years and years to open a restaurant, and it's great to see folks crowding in. Wonderful pancakes, and always a kid or two running around so I don't feel bad about bringing my 2 year old. That said, the kids are more fun than bothersome - it's a great atmosphere. Charlestown needs more great breakfast options, and I'm thrilled to see Grasshopper Cafe open early with their large coffee menu, homemade baked goods, breakfast burritos....yum!
One suggestion: my family (and a few others around) are vegetarian, and we always look for veggie sausage on the menu. It's cheap to buy and freeze, and it makes your customers feel special. The only times I've ventured to Friendly Toast (or farther) have been when I really wanted a veggie-friendly environment....so Grasshopper, please, please get some veggie sausage and tofu in soon! Even meat eaters like a tofu scramble every once in a while!
