This place literally saved me when our group's long day of delayed flights and frantic running thru airports put us in Madison late. Nearly all the restaurants were closing their kitchens, but Glass Nickel's kitchen is open until midnite, AND (this is key) they deliver. For a business traveler with no rental car and not wanting to risk driving in the snow and ice, this is a huge convenience!
I got a sandwich and salad, and even though they said it might take as long as 45 minutes, there was a knock on my door in more like 30 minutes. The sandwich was still hot and the salad greens were still cool, so I give them props for getting the order right and even getting the food to me at a nice temperature. Highly recommend if you are the Middleton area with no room service or few options for dinner. Save this number in your phonebook!
