We love Disney Springs! Because of the shortened park hours on our October trip, we spent more time than ever at Disney Springs. We went there 4 out of 7 nights, when normally we'd spend 1-2 evenings there. We even commented how it would have been a good opportunity to try a stay at SSR since its so easy to walk over from there.
We also like boring American food. Of all the places we've tried, Homecomin' is my favorite. Its TS and does book up. In fact, for most TS at Disney Springs, I'd suggest booking in advance. When we visited DS on the fly back in October, there were many TS taking walk-up but had 60+ minute waits. Some DS restaurants are also on Open Table. In addition to Homecomin', we had a great meals at Wolfgang Puck and City Works, both TS. In the past, we've had a great meal at Planet Hollywood (Observatory) (TS) as well.
There are many times we will do QS when visiting Disney Springs - our favorites are Polite Pig, Chicken Guy, and D-Lux. Blaze is good too, but its a chain that we have at home, so we usually avoid. We also avoid Rainforest Cafe and T-Rex (owned by the same company) because we have a Rainforest Cafe at home, so we'd rather do something more unique to Disney.
We've enjoyed drinks and apps at The Edison, Splitsville, and the Boathouse. We'd return to any of them, but really enjoyed the outside patio with live music at Splitsville.
If you are visiting DS Friday-Sunday, definitely make a reservation for TS and be prepared for it to be busy.
