Suggestions for NHL Road Trip 4/4-4/10

Planning a solo NHL road trip for early April this year, starting in Detroit, doing a loop through Canada and ending in Columbus. Looking for any suggestions on game day experiences/tips for each arena, as well as food suggestions both inside and outside the arena.

The game dates are:

4/4 Carolina @ Detroit (been to LCA many times and always look forward to it!)

4/5 Columbus @ Toronto

4/6 Boston @ Buffalo

4/8 Chicago @ Pittsburgh

4/10 Buffalo @ Columbus
