Restaurants with really uncommon food

Hey folks! I will travel to Houston next month, will stay in Downtown. I love to test something special (once in a lifetime) while traveling, like bear meat in russia, puffins in iceland, fruit bat on the seychelles or beaver meat in Lithuania… same for rare fishes, fruits and vegetable.

So far i found the restaurant "Musaafer" with rare vegetables and fruits (Karvanda, Kokum and Chironji) and a fish I never tried so far (Escolar).

The restaurant "Theodore Rex" with the golden Tilefish.

The restaurant "Kata Robata" with Gizzard Shad and Horse Mackerel.

I know it is a maybe difficult question, but do you know any other places where some unusual dishes are on the menu? I will drive everywhere I can reach in 1 drive-hour… Will be also a few days in Galveston, so this direction is also easy. Thanks in advance!
