You can find handicap parking nearby and there is two entrances to restaurant one of them is through stairs and the other one is through the building which you can find the door above written Martingale and this door is automatically opens if you push the button near the door and there is an elevator which brings you to hostess. Hope I answer your question.
I only recall noticing that there were step stairs to descend to get to the hostess station, but there might be a sightly sloped walkway to access a restaurant you'd have to walk through to get to the Martingale entrance that way. There are parking lots nearby that are within walking distance I believe (you may just have to Google walk the distance). Sorry I couldn't be more definitive in my answers, but I hope this helps.
