Grape soda review: Hot Lunch House Grape Soda 2025-05-26 My aunt and uncle took me to this great sandwich place in Madison, WI and they have a house grape soda so I had to try it. Completely out of league with the usual grape soda I enjoy and review in that it actually tastes like and is made of grape. It purports to have black tea, green cardamom, lemon, and lime in it. And I believe it. It mostly tasted like a nice homemade sparkling juice/soda. Not too sweet. The presentation was top notch. However it didn't have that psychadellic otherworldly hit of toxic grape flavor that I yearn for. 5/10.
