Manila is OK to get around if you are a bit intrepid and patient. I find there is plenty to see and do - and as mentioned above great day tours (if you are prepared for very early starts). Feel pretty safe in most (tourist/business) areas.
Previously we have used Uber to get around without any hassles, but Uber is gone and yet to try Grab. I would steer clear of public transport.
Food is fantastic and readily available for all budgets and tastes. The big bonus for me is English only is required - so navigation and communication is a comparative breeze.
