You need some sort of Metro Fare Card (click on link: there are several options) OR MUCH BETTER your phone and the Metro Q ticketing app (click on link to go straight to Metro info page). The latter is super easy and puts you in control, if you are comfortable using a smartphone for payments. We highly recommend that you download the Q ticketing app and use it throughout your stay.
Note that cash is not a good way to pay on Metro.
To get from the Quad Townhomes to the Museum, use these directions: <https://goo.gl/maps/71qikQ1qJKwFXWfZ8>. I will be guiding you on Monday using these directions. For other destinations such as cafés and grocery stores, see your Cheat Sheet or the appropriately-themed page in this website.
Uber and Lyft are available throughout the city, and is an especially good way to get around if you are sharing a ride.
DOWNTOWN: If you want easy access to some of the more interesting dining, then hop on the train near your townhomes and get off at Central Station Capitol. Find Bravery Chef Hall at 409 Travis St. (a 7 minute walk from the station; click for map). You can read more about Bravery here, but the great thing is that members of your party can try different things from some of Houston's most interesting chefs including Kokoro sushi from Uchi alums, Christine Ha's Blind Goat (inventive Vietnamese), and BOH pizza, which is just great pizza.
Remember to always take the PURPLE LINE train (Palm Center) to go home. There is another line that also runs on the same track. Don't be fooled. Disembark at UH South/University Oaks and you are right there.
If you are feeling even more adventurous, try the food hall at Post Houston. It's a longer walk, but the array of food is a little mind-boggling, the Skylawn should be seen, and the people-watching is great. This is Houston.
Want to support a neighborhood (Third Ward/East End) chef/entrepreneur? Try Roots HTX, a wine bar/bistro off the Leeland stop on the Purple Line (c. 10-15 minute walk from Leeland stop). Backstory here.
There are innumerable restaurants in the Montrose neighborhood. If visiting the Menil Collection, the Menil Bistro gets good marks.
To get to Menil and all other Montrose locations, get on the 25 bus as if you were going to the Museum, but stay on the bus past the Wheeler train stop and you will soon find yourself in the middle of Montrose. Buses return on the same street (Richmond) and Uber usually available in Montrose.
WEIRD STUFF (ONLY LOCALS): How to Survive on Land and Sea is a little unstuffy wine bar popular with the city's wine business people. Although out of the way for most, and just outside downtown, you can get there pretty easily here. Check out the Italian wines and the chefs-in-residence for food.
