I've been to Meat & Potatoes several times and have had some very good dishes and some very.... Interesting dishes. If you are going to try something a little more exotic, like the bone marrow, then I'd suggest you go with a few couples. Have a few couples order things like bone marrow and have others order things like the Mac & Cheese (Out of this world). That way everyone can share and you aren't stuck paying for something you may not care for.
In the end, my experiences at M&P have been pretty excellent. They have a great drink selection and the food is generally very good. I highly recommend the pork chop for dinner. In spite of being very large it was so nice and juicy. I'd say it was cooked to perfection.
