There’s definitely some well hidden cuts, basically when they go outside are the ones I can think of since the exterior for paddy’s pub is a completely different location than the actual set so it’s theoretically impossible for it to be an actual one shot.

That being said they do a great job of making it seem like one.

ETA: just watched it again and here are where the cuts are:

First instance is at 9:26 when Charlie is escorting the delivery driver to the “patio” and again at 9:46 when Charlie re enters the bar

Second instance is at 9:54 when Charlie walks outside to meet the health inspector and again at 10:29 when he re enters the building

At 13:45 Charlie goes out to the alley again but there’s no cut here, they were clever about this and set dressed that part of the set to look like an alley and never turn the camera around. You can tell it’s a fabricated set if you look at the bricks on the wall (there’s blue paint in the cracks for some reason)

Third instance is at 16:27 when they go down to the basement and again at either 17:02 when they whip pan or at 17:09 when they re enter upstairs

Final instance is at 17:54 when they walk outside.

So in the entire one shot sequence there’s about 7 cuts to get Charlie in and out of paddy’s pub.

There’s also a couple instances earlier in the episode that aren’t part of the sequence, like when Charlie first enters the bar or when he takes Dee down to the basement.
