Well given NOC code 6552 is classfied as C so would not qualify as Canadian work experience for the Canada Experience program which needs to be 0,A or B so that would leave you with Express Entry so you would meed to check out your points there

Still surprising that a restaurant could not find anyone for such a role in the whole of Canada and was willing to go through the hassle of an LMIA but guess they were.
Assume you got a TRV in order to travel to Canada as well as the LMIA and you yourself did not pay any fee for the LMIA the restaurant coughed up 1000 dollars for you for the LMIA fee
