There's a Hush Puppy(?) in Burgerpant's fridge if you destroy it.
Key to the locked off room under the Dining Reception protected by metal.
Catty and Bratty has a secret camera surveillance room.

Theres a Temmie hiding behind the poster in the enterance. Also Wingdings things on the wall of the kitchen and the side of keypanel

what is the key to the locked?

Also the bike makes a honking noise when interacted with ( ͡° ͜ʖ ͡°)

I heard that the slimey dog is found by breaking one of the slime puddles, although I couldn't break either somehow.

Easter eggs I know so far :
1 : Temmie behind Mettaton poster in entrance hallway
2 : Dog in fridge in burger pants's kitchen
I have looked trough the map's textures and I found another dog texture with green stuff on it (probably signifying the sewer area) but I couldn't find it
3 :Button to the left of the sofa on the wall that makes gaster appear in the restricted room
To enter the room you must break the metal panel behind a counter , take the key ,bring it to the taped door, break the wooden planks on the door, and gently touch the door with the key( ͡° ͜ʖ ͡°)
Apparently there's 3 buttons but I've only found one so far ;-;
4 : in the left alleyway with the boxes break the smallest box and the secret room's code will appear (I'll let you break it yourself ) this code is the code for the secret checkered room
5 : (here it gets interesting) climbing the box closest to the room corner in the sofa room and getting in the right position will let you look up into a secret part in the ceiling displaying a text written in wingdings " SEND 8 CODE TO TRANSMISSION ADRESS". What this references to is 8 little wingdings simbils scattered around the map (I've found 5 so far)
Their locations are :
- on the left side of the walkway to the core there's a small floppy disk -> "="
- on the wall in the kitchen facing away from the fridge is a pair of scissors -> "#"
- under a table in the dining room there's a thumbs down symbol -> "D"
- on the button pad that opens the secret room on the left side is a zodiac sign symbol -> "^"
- in the pool I the corner closest to the rules sign is another symbol (can't remember this one)
- I suspect the other 3 to be in catty & bratty's area , the sewer area and in the main hall.
That's everything I've found so far
Feel free to complete my findings if you've got anything else
Have a nice day ! ^-^

where did you find the button?
I found one, maybe it's in a different place?

It's in the wall to the left of the pink couch ( it sticks out a little from the wall)
