Hey Chris
Mama’s is 100% authentic Nyonya and much cheaper than Kebaya, which I’d more characterise as “fusion-Nyonya” - its Kebaya taco-like wafers marries Vietnamese “banh xeo” (crisp egg omelette) to Penang’s own “kueh pai tee” (pastry shells), whilst the filling is more Western than Asian. No such “intransigence” at Mama’s - there is a good reason why it has “celebrity” clientele like Penang’s shoe-maker Jimmy Choo and film director, Ang Lee, who make a beeline there for its Penang-Nyonya cuisine. BTW, Mama’s had been renamed Mum’s Nyonya Cuisine in late-2015 - I surmised that there must have been a change of ownership, so not sure if the food is still the same as I’m guessing there is a change of chefs as well.
I’m enjoying Penang food very, very much as compared to KL’s. Penang still keeps to its roots in terms of food preparation - I’ve been in KL for 5 years now, and I’m never really enamoured with KL-Cantonese and Hakka cuisine, which can taste a bit “alien” to my Hokkien/Teochew palate. Penang, like Singapore, is mainly Hokkien and Teochew, so their food has a familiarity which I don’t find in KL. That said, I’d been brought by my Penang foodie friends to some pretty “meh” places - like the cluster of popular hawker stalls on Sungai Pinang Road (next to the Penang Japanese School) yesterday - we tried the Penang curry mee, wanton noodles and herbal duck drumstick with vermicelli, and none of them measure up to the usual standards I’d expected of Penang hawker stalls - and the place was inexplicably packed with local Penang diners - what gives?!
Other than that, Penang is a virtual goldmine of good eats - I’m slowly making my way through old Georgetown - taking notes, speaking to the hawkers, getting to know their history and hopefully able to share them here with other Hungry Onion readers. Being able to speak the local lingo (Hokkien and Teochew) is a definite plus here in Penang - the hawkers open up and often share their experiences, and I’m all ears 
I’m getting up early tomorrow morning to go on another culinary food hunt in George Town. There is a Hokkien noodle place in Pulau Tikus suburb which opens at 7am -by 8.30am, it’s all sold out and the stall will have been wiped clean and closed!! I want to be there by 7am tomorrow.
