I've noticed no one has spoken up about dining near the Ca. Science Ctr.
The Science Center is in Expo Park, which also houses the impressive L.A. Natural History Museum and the L.A. Coliseum -- home the USC Trojans, LA Rams (temporary), and to the 1932 and 1984 Olympics and will be used again for the 2028 Olympics (the Coliseum gives tours but I believe has just started a massive renovation). Expo Park is a major tourist center in LA. but is not surrounded by a touristy area (South L.A. has not gentrified, and while tourist shouldn't consider themselves at risk the area around Expo Park, many do find it intimidating..it's a relatively desperate-looking area). But the (very affluent) USC main campus is directly across the street to the north, and there has been
exponential development on the blocks just north and east of campus adding a lot of new dining in the last 5 years (mostly small QS chains targeting the student population). Today's USC students get to eat much better than I did. Plus, the Science Ctr. and Natural History Museum also have cafes.
If you looking for something more unique to the area, I few miles north in downtown L.A. there is the famous
Phillippe's (110 years old this year, and one of few eateries in L.A. that live up tho the hype) near Union Station, and lots of interesting options in nearby Little Tokyo.
