Hi Lisa..I to have been to the Bubble Room abd LOVED the bread. I understand it is a secret recipe but here is one I think will be a good substitute until you can get back! My memory of the bread is a bit foggy since it's been a while since I was there. Maybe you can see if there is something you could add or subtract for the taste you remember. This is worth trying. Can't remember where I got this recipe..just somewhere on the net. Let me know if you like this....I did.

Cheesy Garlic Bread
1 loaf French bread
1/2 cup butter, softened
1 cup Asiago cheese
1 cup shredded Jack cheese
1 cup mayonnaise
1 bunch green onions, chopped
2 cloves garlic. pureed

Cut French bread into thick slices. Mix all remaining ingredients together. Spread thickly on bread and bake at 350 degrees for 5 to 7 minutes. Place under broiler for about 3 more minutes.
The original recipe cut bread in half horizontally and spread mixture on each half and then after broiling cut it into slices. I thought it had too much topping that way. This will do more than 1 loaf of bread. I keep the mixture in the refrigerator if I don't use it all at once. You could probably use Parmesan cheese instead of the Asiago.
