Must-eats
The two places not to miss.
More food
Curry, burgers, takoyaki and fried-everything, for whatever the mood is.
Coffee
Osaka does great coffee. Honmachi has three of these within a few minutes' walk.
Drinks
All three are in Namba, a few minutes apart, so they work as a little bar crawl.
Sights
Nightlife, a castle, and two half-day trips out of the city.
