Any Food / Men’s Clothing Recs whilst in Shanghai?

As the title suggests, does anyone have any good food recs (traditional/modern shanghainese + general ‘must-try’ chinese foods) as well as any men’s clothing + antique shopping recs? (streetwear, minimalism, technical wear) I’m going to be visiting a friend of mine in Shanghai during December for 10 days (1 of course will be DisneyLand!) and would love some suggestions on where to eat and shop! All suggestions are greatly welcomed and a big thank you in advance for all the help! Have a fab day ahead!
