Yes, DH and I went to Let's Dish! in Timonium, MD over the summer. We liked the meals and the website had a section to breakdown the cost to show it's actually a little cheaper than buying the ingredients yourself and making the dishes.
It was a fun activity too! It's not something we would do all the time, but we are definitely planning on going back sometime. It is convenient to have meals ready to cook up. Some are ready to cook as is, others you need to defrost first.
I noticed some of the dishes could have been a little more seasoned but I heard that they don't overly season it so people can make it to their liking. And the neat thing is you can omit or add items too. If you don't like mushrooms, just don't put them in. If you like more cumin, just add it! You probably have be careful with the larger ingredients though (like chicken, etc.) because I think they only have a certain amout available based on the selections people submitted for their session.
Overall, I thought it was a fun experience that gives you a bunch of yummy food in the end!
FYI to anyone in the Baltimore area wanting to try Let's Dish!, I have seen $10 off coupons several times in 'Baltimore's Child' magazine...
