I would appreciate it if you could review my 4-day, 3-night Busan itinerary

‌It is scheduled for a Sunday to Wednesday in mid-October.
Arrive at Haeundae accommodation on Sunday afternoon.
Have eel for dinner at Donggyeong Bapsang in Suyeong-gu (Haemok is fully booked), then take a walk around Haeundae and Gwangalli.
Day 2: Visit Chinsu Park, then visit Choryang, Nampo, Busan Tower, Gwangbok, Jagalchi, and famous nearby markets.
Day 3: Geumgang Park, Beomeosa Temple, Oncheoncheon Stream, Dongnae Fortress, Momos Coffee, and the area in front of the military base.
Day 4: Have Sokssiwonhan Daegutang (spicy cod soup) and ride the Mipo ~ Songjeong Beach Train.
This is my planned itinerary.
Are there any recommended places or restaurants around the Day 2 and Day 3 areas?
